Towards an Understanding of Oversubscription in Cloud

Open access to the papers is sponsored by USENIX.

Oversubscription can leverage under utilized capacity in the cloud but can lead to overload. A cloud provider must manage overload due to oversubscription for maximizing its profit while minimizing any service level agreement (SLA) violations. This paper develops an understanding of oversubscription in cloud through modeling and simulations, and explores the relationship between overload mitigation schemes and SLAs.

Authors:

Salman A. Baset, Long Wang, and Chunqiang Tang, IBM Research
